Details:

Hi,

When using multibyte string egrep uses re_compile() and re_search()
from glibc to deal with regex and glibc accepts '\s' as equivalent
to '[:blank:]'.

When using single byte string egrep uses dfacomp() and dfaexec()
which does not implement '\s'.

How to reproduce it:
$ echo "     root=/dev/sda" > /tmp/input
$ LANG=en_US.UTF8 grep -E "^\s*root" /tmp/input
     root=/dev/sda
$ LANG=C grep -E "^\s*root" /tmp/input
$

Attached a patch to implement '\s' handler.
